How Long Do Short URLs Last?
There is no universal expiration period for shortened URLs. Their lifetime depends on the service, its policies and whether the link or destination remains available.
Why a short URL can stop working
A link may be deleted, disabled, moved to a different destination, or affected by a service or domain problem.
How to protect important links
Use a reliable service, test important links periodically and keep the original destination documented. For long-running campaigns, avoid depending on a link you cannot maintain.
Short URL versus destination lifetime
Even when a short link still exists, its destination may disappear or require new permissions. Both sides should be checked.
